As shown in Figures 2 to 4, the clamping for multi-color injection molding machine that this utility model embodiment provides, comprising: For fixing the first fixed plate 2 of the first half module 91, the second fixed plate 3 for fixed second half mould 92, oil cylinder combination, brother woods Post 1 and for carrying the loading plate 5 of oil cylinder compound action power, the first fixed plate 2 is passed through brother's woods post 1 with loading plate 5 and is connected as Rigidity is overall；One end of oil cylinder combination is connected on loading plate 5, and the other end is directly or indirectly connected in the second fixed plate 3, oil Cylinder combination is moved along the length direction of brother's woods post 1 for driving the first fixed plate 2, it is achieved the first fixed plate 2 and second is fixed Plate 3 does towards or away from motion, thus realizes matched moulds or die sinking；Second fixed plate 3 is rotating disk, can be in frame 7 Rotate, thus realize the replacement of the second half module 92.Oil cylinder combination includes two actuating cylinders 61/62 and two that movement locus is identical Individual slave cylinder 4/40, slave cylinder 61/62 be arranged in parallel and scattered distribution is on loading plate 5.Wherein, actuating cylinder 61/62 For driving clamping to realize matched moulds and die sinking campaign；During die sinking, slave cylinder 4/40 passive exercise；During matched moulds, driven oil The main stroke of cylinder 4/40 does passive exercise, be near completion matched moulds or matched moulds complete after slave cylinder 4/40 actively have an effect thus realize The matched moulds of bigger pressure clamp force.In the present embodiment, all slave cylinders 4/40 share pressure oil pipe, and all slave cylinders The pressure of 4/40 output is identical.It is understood that in this utility model embodiment, the quantity of actuating cylinder can be two Above, the quantity of slave cylinder can also be two or more.It addition, oil cylinder combination can be used for driving the second fixed plate 3 edge The length direction motion of brother's woods post 1, it is achieved the first fixed plate 2 and the second fixed plate 3 are done towards or away from motion, thus realize Matched moulds or die sinking.

Specifically, actuating cylinder 61/62 includes top interface and lower section interface respectively, all actuating cylinders 61/62 upper Side's interface is communicated by pipeline 65, and is connected with oil path distributor 82 by pipeline 63 further, all actuating cylinders 61/62 Lower section interface is communicated by pipeline 66, and is connected with oil path distributor 82 by pipeline 64 further.

Further, two slave cylinders 4/40 are along the length direction scattered distribution of loading plate 5, and two slave cylinders 4/ 40 are separately positioned on loading plate 5 along its length near the position of brother's woods post 1.

Further, slave cylinder 4/40 all includes hydraulic oil chamber, this hydraulic oil chamber include one can selectivity with The pressure oil pipe 45 of the high pressure liquid force feed connection on oil path distributor 82, also includes to select with the normal pressure hydraulic oil in fuel tank 81 Property connection normal pressure oil pipe 42/47, the pressure oil pipe 45 of two slave cylinders 4/40 is connected, the caliber of normal pressure oil pipe 42/47 Diameter much larger than pressure oil pipe 45.

Further, pressure oil pipe 45 and the connection of high-pressure and hydraulic oil pipe line and disconnection are by the valve on oil path distributor 82 Controlling, normal pressure oil pipe 42/47 is controlled by another valve together with disconnecting with normal pressure hydraulic oil.Preferably, pressure oil pipe 45 with Connection and the disconnection of high-pressure and hydraulic oil pipe line are controlled by the electromagnetic valve on oil path distributor 82, normal pressure oil pipe 42/47 and normal pressure Being controlled by pilot valve 41/46 together with disconnecting of hydraulic oil.

Further, the control fluid of pilot valve 41/46 is connected with oil path distributor 82 by oil pipe 43/48, first Control fluid on-off in pilot valve 41/46 is by the electromagnetic valve control realization on oil path distributor 82.When the first fixed plate 2 During with the second fixed plate 3 move toward one another to setting position, the normal pressure oil pipe 42/47 that pilot valve 41/46 controls is switched to by connection Disconnecting, the connection status of pressure oil pipe 45 and high-pressure and hydraulic oil pipe line that electromagnetic valve controls is switched to by disconnection and connects, with realization The closing of the hydraulic oil chamber of slave cylinder 4/40；At the initial time of die sinking, get final product the first fixed plate 2 and the second fixed plate 3 When will do opposing motion, the normal pressure oil pipe 42/47 that pilot valve 41/46 controls is switched to connection by disconnection, and electromagnetic valve controls The connection status of pressure oil pipe 45 and high-pressure and hydraulic oil pipe line switches to disconnection by connecting.

Further, the clamping of this utility model embodiment also includes the position inspection for detecting above-mentioned setting position Surveying device, the conducting of pilot valve 41/46 and the position closed according to position detecting device are made to switch.Preferably, pilot valve 41 is Normally open, normally open is more energy efficient.

Further, in this utility model embodiment, the diameter of slave cylinder 4/40 is straight more than actuating cylinder 61/62 Footpath.

In this utility model embodiment, slave cylinder 4/40 shares pressure oil pipe 45 and can ensure that the driven oil of scattered distribution Cylinder 4/40 output pressure is identical, i.e. can guarantee that accurate mold clamping force, so that it is guaranteed that moulding quality.Actuating cylinder 61/62 This structure of common conduit 63/64 can ensure that die sinking, matched moulds process stabilization, steadily.

In sum, the slave cylinder 4/40 of this utility model embodiment uses decentralized layout structure, can subtract during matched moulds Little first fixed plate 2 and the elastic deformation of loading plate 5, stop the first half module 91 and the second half module 92 produces skew dislocation, injection Product is without overflow edge；The pressure oil pipe of the slave cylinder 4/40 this structure that is connected can ensure that during matched moulds the equilibrium of multiple oil cylinder working-pressures, Mold clamping force is stable；The oil cylinder combination being made up of actuating cylinder 61/62 and slave cylinder 4/40 can give full play to minor diameter actively oil The strong point that cylinder 61/62 moves soon, slave cylinder 4/40 pressure is big, on the premise of fully ensuring that high pressure matched moulds locked mode, reduces Die sinking, burn close time.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this Any amendment, equivalent or the improvement etc. made within the spirit of utility model and principle, should be included in this utility model Protection domain within.
